Lobster Facts

1. Lobsters never stop growing.

Unlike humans, who grow until adulthood and pretty much plateau, lobsters keep growing for their entire lives. Each time they molt, they can increase 20 percent in size.

2. Lobsters don't age the way most animals do.

Aging as we know it is tied to telomeres, or protective tips on the ends of DNA inside animal cells. Each time a cell divides, its telomeres shorten, until eventually the cell can't divide anymore. But lobsters have a special enzyme that lengthens their telomeres, keeping them younger longer. How do we sign up for that?

3. But that doesn't mean they live forever.

If they make it to old age without being eaten, lobsters often die shell-related deaths. Molting takes so much energy, it can kill older lobsters. If lobsters live long enough, they even stop molting altogether and can die of shell infection or even shell rot.

8. They make the worst ridesharing passengers.

9. Lobsters have a thing about pee.

First of all, they pee out of their faces from the antennal glands under their eyes. Their pee can project seven body lengths. And they use it to communicate about everything, including mating and fighting.
